It appears that there is no insulating material between the Aluminum ribs and the Aluminum roof sheet (I can't tell for sure).  If not that creates a large thermal "short" allowing direct thermal conduction from inside to outside (heat moves from hot to cold).

 

Seems to me a thin layer of insulating material (a sheet or tape) between each rib and the skin would minimize the thermal short and help cut down heat loss.  Filling the Aluminum channel with form would also help as well as minimize a volume where vapor can condense and the leak out.

 

I have noticed ice forming on screw heads in the ceiling of our FWC and that got me wondering if the aluminum frame is in thermal contact with the skin.  I think it is.

 

If there is more information on this I am interested in reading about it.

 

Regards,

Craig

The roof frame is completely covered in a good closed cell tape. It looks like the metal in some pictures.  If you look down to the picture with the roof skin you will see the tape on the edge. The insulation that is doubled up in the roof has a combined R value of almost 7. That is more than double of solid insulation.

IMO the "bat" type insulation is easier,more cost effected,and fills the areas better.

With ridged type each piece has to be cut to fit it's specific location and if not cut exactly to fit could leave space between framing and insulation.

Hi Frank,

 No the bat type that we use cost much more than the solid to purchase. It is two hours faster to install. It has a better R value than the solid.

Good discussion on the roof. I, like probably most others here, have read and heard lots of opinions on roofs and insulation. The Lady & my decisions about camper choice and construction are based from an experienced pop up camper user's perspective. I also know how to build things. We backcountry ski out of our camper and we enjoy bitterly cold desert winter mornings. We want a warm camper. That drove two decisions on our new camper - a small non slider window against the truck cab and the insulation in the roof and walls that ATC uses in their standard build.

This camper build is so cool on so many levels from seeing it transform from a stack of tubing and lumber to become a camper to daydreaming about all the wonderful adventures ahead this camper will play a prominent role in. It is hard to contain our excitement.

 

I was back down at the factory to check on progress and make some decisions. It is hard to stay away and again I thank the guys for their patience with me and my curiosity.

 

All the 12V wiring has been routed in the walls.

The roof is ready for lift panels and then joined to the main camper section.

The Lady’s choice of vinyl was laid out with the pattern for the floor.

It was a perfect fit.

i had a small leak, easily fixed but the insulation (as far as i could tell) seemed to soak up the moisture, more than a a solid piece would. Do the FWC campers have the same bow in the ceiling or is that an ATC thing?

Yes they do. From what I can tell from the pictures, the structure looks identical.

What a difference a day makes.

 

The inside paneling has all been installed and the window/exterior openings have been cut out.

 

 

gallery_1902_710_3546.jpg

 

 

 

gallery_1902_710_108516.jpg

 

 

The insulation is in the walls and the aluminum siding is going on.

 

 

gallery_1902_710_33879.jpg

 

 

Also in place for a test fit is the rotopax mount on the rear wall.

 

 

gallery_1902_710_118268.jpg

 

 

Brad and Chad continue with installing the siding.

The Yakima Tracks are in place on the roof along with the plug for the solar panel.

Marty and my attention went to the placement of the bottom board I will use to build our cabinet. It would help to get it laid out now for placement of the furnace and the propane box.

 

Brad helped out by double checking the dimensions and that it is square to the extension below from the floor pack. This will be my cabinet for two bottom drawers.

After we fit the furnace in its place, it is then pulled out and test fired and ran for awhile to burn off any oils.

 

 

gallery_1902_710_82917.jpg

 

 

My future work space has been established and the ATC guys got right on finishing up the siding and trim.

 

gallery_1902_710_69653.jpg

 

 

Pretty exciting, isn’t it! The Lady said this morning that all she’s been dreaming about is camper parts and cold mornings “out there” where we wake, alone, and wait for the sunrise.

Thanks Marty.I like the "bat" type better than ridged,glad you use that.

Interesting that it would cost more.Oh well it's worth it.

Figured it would be faster to install and fill the space better.

Thanks to you and Ski for showing the construction of the campers.Very nice.

Frank
